Description

compare_thresholds is a helper function for thresh_gam. It test whether a specific threshold value leads to a new splitting of trainings observations in the threshold variable in comparison to the previous threshold value. Returns FALSE if the change in the t-t_val does not result in a new grouping of threshold values (above and below the t_val).

Usage

1
compare_thresholds(t_val, t_var)

Arguments

t_val

A vector with threshold values.

t_var

A vector with pressure values of the threshold variable.

Value

The function returns a tibble with one row for each t-val and two columns:

t_val

The input vector of threshold values.

change

logical; if TRUE, the respective threshold value lead to a new splitting of trainings observations in the threshold variable.
